Top Elixir development companies in 2026: 8 firms compared

‍

Elixir has a small consultancy scene, and the Elixir development companies in it are good at quite different things. So "who's the best Elixir shop?" is the wrong first question. The better one is what you need a partner to do: build something from scratch, rescue an app that's buckling, add senior engineers to your team, or give your developers an expert to call when they're stuck.

A note before we start: we're Curiosum, and we're one of the eight companies on this list. We've put ourselves first because it's our article, but we've tried to make the other seven profiles fair and useful. Every claim about them comes from their own websites, case studies and public client reviews. Most of the numbers are self-reported by each company, including ours, so treat them as claims, not independent benchmarks.

Curiosum: Elixir development company for backend ownership (that's us)

We're an Elixir software house based in Poznań, and every new project we take on involves Elixir. We work as a team extension, deliver projects end to end, or provide Elixir consulting. So far, that's more than 50 delivered projects, for companies at very different stages, including:

• Twine: a Swedish startup connecting HR and payroll systems
• Thoro.ai: autonomy software for warehouse robots
• Digiforma: a training platform used by thousands of French companies
• Lonely Planet: the travel publisher, part of media group Red Ventures
• MEDICE Health Family: a pharmaceutical group, including its menopause app femfeel

Beyond client work, we run Elixir Hub, the Elixir Newsletter (around 2,000 subscribers) and the Elixir Survey (around 1,900 respondents). We wrote the free Elixir Adoption Guide and maintain Permit, Kanta and Contexted. We're also Hologram's main sponsor, and its creator is part of our team.

A good fit if you want one Elixir team to own your backend, with React or React Native available when you need it.

Software Mansion

Software Mansion is much bigger and broader. It's a Kraków company best known in the React Native world, with over 400 people, but its Elixir work is serious, especially anywhere media is involved. It created Elixir WebRTC, along with Membrane for media processing, LiveDebugger for LiveView apps, and Popcorn, which lets Elixir run in the browser.

Its client work follows the same pattern. For Dscout, a user research platform, it moved an admin panel from Ruby to Elixir and modernized the frontend. For Turn.io, a messaging platform that runs on WhatsApp, it added real-time voice, and reports 250% more weekly voice calls.

If your product's hard part is audio, video or WebRTC, this is probably the first call to make.

Erlang Solutions

Erlang Solutions has been in the BEAM world longer than almost anyone and is now part of the Trifork Group. Its menu goes beyond building features: Elixir consulting, development, support, code and architecture reviews, a security audit, training and certification.

The Bleacher Report case shows what that looks like in practice. The sports site brought Erlang Solutions in after shipping its first Elixir system, to check it hadn't built in problems for later. The team reviewed systems on site, found that its Docker setup was slowing builds and deployments, did regular code reviews, and cleared downstream bottlenecks by chunking data. Erlang Solutions' headline figure is 150 servers cut to 8.

Security audits are another strength. HR integration platform Twine went through Erlang Solutions' SAFE audit for Elixir and received a report with findings and recommendations. (Twine is also one of our clients.) The company also stands behind MongooseIM, its Erlang messaging server.

A strong fit if you need a second opinion on an existing system, a security review, training, or ongoing support.

DockYard

DockYard is a product studio, so it covers strategy and design as well as code. That matters when your problem isn't only technical.

Veeps, a ticketed livestream platform, is the standout story. DockYard ran a technical discovery with Veeps' stakeholders before building. A big reason Veeps hired DockYard was to make sure the rewrite could survive the rush of traffic when concert tickets go on sale. The official Elixir case study adds the results: a full rewrite in about eight months, 2 Elixir nodes doing work that previously took 20 Rails nodes during big events, and 83 times more concurrent users. The Flame On profiling library came out of that project.

One caveat: DockYard created LiveView Native, but the main repository was archived in February 2026. If a proposal leans on it, ask who maintains it now.

Worth considering if you need product thinking and UX alongside Elixir engineering.

Alembic

Alembic is an Australian consultancy with an unusually deep bench in Ash. Two of its people, Rebecca Le and Zach Daniel, wrote the Ash Framework book for The Pragmatic Programmers. Zach created Ash, and Rebecca has joined the Ash core team. Alembic also sells Ash Premium Support, a subscription with direct access to its Ash experts.

Its healthcare case study has the most eye-catching number on this list. After replatforming onto Elixir and Ash, the client's cloud bill reportedly fell from about $60,000 a month to under $10,000, and all 1,000 customer locations moved over at once without disruption. For Soluna Computing, Alembic helped move off a no-code platform to Elixir, built metrics collection for matching compute demand to renewable energy, and helped plan the wider migration.

If Ash is in your plans, this is the obvious conversation to have.

Appunite

Appunite moved from Rails to Elixir back in 2015 and is built around embedding engineers in client teams. It's refreshingly open about pricing: a monthly retainer from $11k per developer, with team size adjustable on one month's notice.

Its longest-running Elixir story is Allegro Lokalnie, the C2C marketplace from Poland's biggest e-commerce company. Appunite recommended Elixir for the MVP and kept working on the platform as it grew. Later, it says it cut the product's Google Cloud costs by 80%. Appunite's own write-up describes that saving as coming from Google Place Autocomplete spending.

At Contractbook, three full-stack Elixir and React developers built integrations between Contractbook's Automation Builder module and outside tools, working closely with the client's product managers. Appunite also maintains Mockery, a mocking library for async Elixir tests.

Good for teams that already have product leadership and need more hands that can work without much supervision.

WyeWorks

WyeWorks, from Uruguay, started as a Rails shop, and one of its founders, Santiago Pastorino, joined the Rails core team. It now works across Ruby, JavaScript, Rust and Elixir, which makes it a good match for products where Elixir is only one part of the stack.

At Packlane, WyeWorks took ownership of the core product and put a separate frontend team on finishing and launching Shiplane. For Argos, it reworked an Elixir and LiveView education platform and added SSO and payments. And at the bank HMBradley, its engineers helped migrate the banking core from Go to Elixir and delivered features independently.

For balance: some Clutch reviewers said WyeWorks could make its estimates more accurate. That's worth raising early.

Dashbit

Dashbit is different from everyone else here. It doesn't build your app. It's José Valim's company, and it sells a development subscription. It's charged per seat, and each developer on a seat gets unlimited support and code reviews.

The pitch is simple: you get help from the people who make the tools. Dashbit built and maintains Broadway, Ecto, Nx and Elixir itself, and takes part in Hex.pm and Phoenix. It also has a Livebook team.

Demand is the catch. In early 2025, Dashbit said the wait to start had averaged around 12 months, and it was growing its subscription team from three to four engineers. Ask about current wait times before you plan around it.

The right choice if you already have developers and want the best possible backup on architecture and hard production problems.

How to pick an Elixir development company

Whether you want to hire Elixir developers into your team or hand over a whole project, most teams can rule out half this list by being honest about what they want the partner to own. Then ask each remaining company for a project that looks like yours, the names of the engineers who'd actually work on it, and a first scope with deliverables you can check. Settle early who owns architecture, releases, incidents, and handover, because that's usually where engagements go wrong.

FAQ

What is the best Elixir development company?

It depends on the job. For an Elixir team that owns backend delivery, from startup products to enterprise platforms, Curiosum is a strong fit. For audio and video, look at Software Mansion. For audits and security reviews, Erlang Solutions. For expert guidance while your own team writes the code, Dashbit.

How do I hire Elixir developers?

You can hire in-house, extend your team with a specialist firm such as Curiosum, Appunite or WyeWorks, or hand over a whole project. Team extension is usually the fastest way to add senior Elixir experience, because the pool of experienced Elixir engineers is small.

Is Elixir a good choice for startups?

Often, yes, especially when a product needs real-time features or has to handle a lot of concurrent users without a large team. Twine, a Swedish HR integration startup founded in 2022, built its platform on Elixir to manage complex data flows securely. Thoro.ai uses Elixir to coordinate a global fleet of warehouse robots.

What's the difference between Elixir consulting and team extension?

With consulting, experts review your architecture, code or security while your team keeps building (Dashbit, Erlang Solutions, Curiosum). With team extension, the partner's engineers join your team and write production code alongside yours (Curiosum, Appunite, WyeWorks).
